The Chicago Cubs' historic World Series win breaking a 108-year drought was considered so unlikely, pollsters put it right alongside a Trump presidency.

But Nate Silver, statistician and editor-in-chief of FiveThirtyEight, is not laughing now. "Reminder: Cubs will win the World Series and, in exchange, President Trump will be elected 8 days later," he tweeted on 11 May this year.

The Cubs' historic win, which was almost predicted by Back to the Future, may have moved Bill Murray to tears, but Trump supporters - many of whom dislike Silver, to say the least - were equally joyful.

"IT'S HAPPENING," tweeted @KGBVeteran. "Nate has the monkey paw version of future sight. It always shows him what he DOESN'T want to see, and it comes true," said @TheHippestHippo.

"This might be the first accurate prediction of the year for you, Nate Aluminum," tweeted @comicsea44. "Apparently you used all your prediction powers on one single tweet this year," @hunterswogg said.
